Large ground-based laser beam interferometers are presently in operation both in the USA(LIGO) and in Europe(VIRGO) and potential sources that might be detected
In the collapsar scenario of the long duration Gamma-Ray Bursts (GRBs),multi-TeV neutrino emission is predicted as the jet makes its way through the stellar env
AGNs with hard γ-ray emission identified so far are radio-loud.III Zw 2 is a radio intermediate AGN with a relativistic jet.We study its spectral energy distri
